1  Test a hypothesis involving a proportion as in #916 pp.49899. (A correct answer includes the test statistic, the Pvalue and a conclusion in English) 
Indicates a ruler is required to create the answer for the problem. 

Indicates there is a routine on the calculator which quickly does most of the work for the problem 

Indicates the problem takes some time to work correctly. 

Indicates finding the answer requires some heavy thinking. 
WARNING: Every semester a student will tell me at the end of the final period, "If I had more time, I could finish." I do not doubt this at all. All the problems on the final exam are similar to ones in the textbook, so if you read and study the textbook long enough, you could finish the final. Unfortunately, you just have the time scheduled for the final exam period.
Your objective is to organize what you learned during this course so you can answer as many problems as possible in the time allotted. You must read and practice problems before the final exam so you know what formulas to use and where any needed information is given in the problem statements. The main reason the final exam is open book is to allow you to look up any formulas you might have forgotten  not to read the background material needed to do each problem.
Most students can earn about 90 out of the 120 possible points. Each semester, there are students who earn 108 points or more on the final, but there are also students who earn less than 72 points on the final.
